What does a bad MAF sensor on a Nissan Juke mean?
The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Nissan Juke’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold.
What happens if my MAF sensor is bad?
The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Nissan Juke’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Juke’s ECU.
What causes rough idle after replacing mass air flow sensor?
Replaced air filter and maf sensor. Problems with vehicle turning off seemed to go away but now I have a rough Idle. Car will drop below 1000 rpms and then rev back up to over 1500 like it wants to shut off. Idle problems seem to go away when maf sensor is disconnected. Car throwing codes p0171 and p0102.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.

How to replace the mass air flow sensor?
Here is the tsb on replacing the Mass Air flow sensor. You only have to reprogram the computer if necessary. Here is the instructions. See for yourself. 1. Remove the air filter element. Then, vacuum out all dust/dirt/debris found inside both halves of the air filter housing.
